One of our Client has got CAS NLB with 2 exchange 2010 server in the same site.
The Databaseas have RPClientaccessServer pointing to the CASArray.
All the exchange server are 2010 SP2 rollup 3.
When one of the the CAS server goes down, they need to restart the outlook to connect back again. Is this the normal behaviour with CAS NLB or where can start looking for this issue.
All the servers are on Virtual (vmware) and CAS NLB is using multicast
